I have the following string filename(only has one double quote at end):
'arto.py"' I want sed to do a search and replace something with "Results/arto.py". I tried the following but it complained because of the last quotation mark.
sed -e "s/^filename=.*/filename=\"Results/$filename/g" $I > temp ($I is the current file in a loop)
Does kornshell have a chop command like PERL? I could solve this problem by chopping off that trailing " so sed doesnt complain and just hardcode both quotes as part of the replacement string
Any ideas? Thanks.

sed -e 's/.$//g' <filename> should delete the last character of each line in the file.

Alternatively
echo "some string" | sed -e 's/.$//g'
but be sure to escape special characters in the string.
